PRINTING AND FOLDING MACHINE.

SPECIFICATION forming part of Letters PatentNo. 753,169, dated February 23, 1904.

Application filed May 14, 1901. Serial No. 60,196. (No model.)

cut into lengths for delivery with or without further folding, though in so far as the main features of my invention are concerned the paper or webs may be manipulated in other or known ways, as by using the longitudinal folder to associate web-sections or narrow webs or by having the transverse cutting precede the folding.

This invention is intended more especially for use in locations where the walls of the building or the positions of supports or other machinery prevent the straight run of the web through both printing and folding mechanlsms.

In its general organization the present invention consists in perfecting printing mechanism delivering its web (or. webs) in or traveling in one plane, a suitable folding mechanism arranged so that the general direction of travel of the paper therethrough is at an angle to the first-named direction, said angle being other than a right angle, and means interposed between the printing and folding mechanisms for guiding the web from one. to the other of said paths of travel. The delivery may be located to suit the requirements of the particular case, though, generally speaking, it is preferable to locate it on that side of thefolding mechanism left vacant by the angle between the press and folder.

The preferred form of the invention is illustrated in the accompanying drawings, forming part of this specification, in which- Figure 1 is a diagrammatic side elevation of a printing and folding machine in which the invention is embodied, and Fig. 2 is a partial plan of the same.

In the drawings I have omitted all driving mechanism, as the same may be of any character suited to the particular case; also, the common framework in which the parts are mounted in appropriate manner is omitted; also, the inking and other mechanisms the showing of which is not essential to an understanding'of the present invention are omitted from the drawings for the sake of clearness.

The driving mechanisms hereinafter referred to are such as a mechanic skilled in the art can easily supply.

In illustrating my invention I have elected to show three web-perfecting printing-presses, A B C, arranged one above another, anda longitudinal folder F, set at such an angle to each other as that the courses of the paper in passing through the presses lie in one vertical plane, as it were, while the course of the paper in passing to the folder is at an angle other than a right angle'to the said vertical plane. Intermediate the printing and the folding mechanisms I arrange the means for guiding the paper from one to the other of said vertical planes.

The reference D marks the distribuitingcylinders of a suitable inking apparatus.

The web a receives impressions thereon from the first-impression and plate cylinders t" p on its upper side and impression on its under side from the second-impression and plate cylinders 15 19 of the press A as the web passes therethrough. The webs b 0 receive impressions on their under sides from the firstimpression and ,plate cylinders t" 30 and on their upper sides from the second-impression and plate cylinders 17 p of their respective presses B and C. From the presses these webs are led about suitable guide-rollers d. The web a passes between a roller 6 and a paste-applying disk f and receives when it is so desired a line of paste along its upper side. Then the web (4 passes about an angle-bar g backward to and about a lower guide-roller i2, and over a roller 7c at the top of the folder F. In passing from the roller 6 about the bar g to the lower roller h the direction of travel of the web is changed from one plane to another,

forming an acute angle with the first plane, the rollers e and it being set at an angle to each other and the bar g being at an angle'to each of said rollers. The roller is parallel with the cylinders of the presses, and the rollers h are parallel with the roller 75. The bar 9 is suitably grooved to permit the line of paste on the web a to pass it without touching. The Web Z) passes from a roller (Z to and between a roller e and a paste-applying disk f, where it may receive a line of paste along it, as in the case of the web a. From the roller 0 the web 6 is led around a roller m, parallel with the cylinders of thepresses, and which is grooved circumferentially to prevent the paste from touching it, and to an angle-bar oz and thence about rollers'h to the roller k. The roller m is journaled in arms 0 of a shaft p,which is journaled in the framework of the machine, whereby the-position of the roller on may be varied in order to secure register with the web (0. Suitable gearing (not shown) may be employed to drive the roller m in all positions thereof at such speed as will cause the said roller, acting in conjunction with the rollers or friction-disks q, to keep the web 6 taut and to feed it forward to the angle-bar n at the speed at which the web is delivered by the press B. The disks q are mounted on a shaft 8, which is carried by arms 2. from the shaft p, so that the rollers or disks q and the roller m have the same external center of motion. From the bar at the web 72 passes to a roller it, where it is associated with the web a and is caused to adhere thereto whenever paste has been applied to the upper side of the web a. The web 0 passes from a roller (Z to and about a roller 14, thence to and about an angle-bar o, to and about a roller 7L, and to the roller 70, where it is associated with the webs a b and is caused to adhere to the latter whenever paste has been applied thereto. A set of tapes w, running on rollers or pulleys m y, sustains the web 0 between the rollers cl and a, the tapes being run at such a speed as will cause them and the roller a to keep the web taut and deliver it to the angle-bar Q) at the same speed it has when leaving the press C. The pulleys y are supported by arms from a journaled shaft 2, whereby the tapes may be kept taut by proper adjustment of the shaft and arms, as will be understood by those skilled in the art.

The rollers e, h, and 7s and also the tapes w, and rollers m and u are driven preferably at a speed slightly greater than the speed of the cylinders of the presses, whereby the webs are kept taut and drawn about the angle-bars, and I remark that the register of the webs may be secured in any known manner and that all the ther folded and out transversely prior to their delivery as separate cuts or copies and that the delivery may be located with respect to the folder F as may be most convenient, the forms on the plate-cylinders being arranged accordingly; but in general it is desirable that the delivery take place on that sideof the folder F where the folder would be placed in part were the webs to run straight through both printing and folding mechanisms without being turned from one to another plane or run in two directions forming an acute angle with each other, as this economizes space and the delivery does not project so far beyond the general outline of the machine, and it is obvious that supporting-tapes may be used for all of the webs as well as for the web 0; also, that one or more of the printingpresses may be used, the remainder being silenced for the time being, and the printed web or webs be associated and folded, cut, and delivered.

It is remarked that each web before being associated with any other web is drawn around the bar placed at an angle to the course of the web, so that each web is smoothed out by its said bar before any association occurs, thus avoiding folds or wrinkles, with possible tears, in the folded products delivered by the machine.

It will be observed that the web a after leaving the printing-press passes to the bar 9 and backward to a roller h and that the Webs b 0 first pass over rollers m a and then to the bars n o. This change is necessary, since it is desirable that the sides of the webs first printed should come in contact with the turning-bars, the surplus ink on that side having been taken off by the contact with-the secondimpression-cylinder blanket during the taking of the impressions on the other side and the web co going into its press differently from the way the webs 5 0 go into their respective presses.

The reference E designates the angles formed by the sides of the framework wherein the presses and the folding mechanism are severally mounted.
